When it comes to learning geometric tolerancing, some people opt for buying a book to read, or nowadays they can sign up for an online self-study course. The advantages to this are twofold: the ability to study at your own pace, and it is usually less expensive for an individual than a full training seminar. Traditional training with an instructor in the same room is sometimes more expensive (not always, depending on the number of students) but the huge advantage here is the ability to ask questions and have the instructor relate the concepts to your specific needs. If people from different areas attend the class together (design, CMM inspection, manufacturing), then they can also learn from each other and be in sync when GD&T issues come up in the future.

This has two distinct advantages: First, because an on-site is targeted to one group, the instructor is able to customize the presentation. I always invite participants to bring sample drawings to class to help generate discussion and get them to think more about the correct application of GD&T to their actual parts. The second advantage is cost. The on-site package is usually less expensive as compared to individual tuitions at a public course, although there is a threshold number (usually around 5 or 6 people) needed to make the savings apparent.
